Abstract

This paper compares different receiver architectures for UWB radio communication in the 3.1-5GHz band, targeting data rates up to 10Mbps, in terms of their BER performance and power consumption. A receiver, in which some correlations are carried out in the analog domain seems to outperform a fully digital receiver, commonly suggested for baseband UWB. This paper proves that for equal processing gain requirements the partially analog receiver consumes 7 times less power per received bit than the fully digital one.
